I am selling an ART Studio V3 tube microphone preamplifier. I purchased this several years ago and used it for recording at home, but I haven't been using it recently, so I am selling it. It has been well-maintained since I bought it, and since it was only used indoors, there are no noticeable scratches, and the operation is also fine. The vacuum tube has been replaced from the original with a GROOVE TUBES GT12AX7C. I still have the original tube, so I will put it in the empty box of the above vacuum tube and send it together. The included accessories are the Soundhouse AC adapter and the above-mentioned vacuum tube. There is no instruction manual, but it's not that difficult as you just select a preset and adjust the level. I will pack it securely in an empty box and ship it. I will gradually lower the price, so I will not respond to price reduction comments. If there are no purchases after a certain price reduction, I will return the price for a long-term sale, so please purchase it at a good time.
